Hypobaric Chamber for Oral Flora Study in Simulated Spacecraft Environment

Abstract

A chamber to house two marmosets in a space-simulated environment was built and tested. The chamber was used in three experiments of two weeks duration each to study changes in the oral microflora of marmosets exposed to an atmosphere of 70% oxygen and 30% nitrogen at 5 psi.
